So I broke the high e string on my guitar and it could be a long time before I replace it. I am afraid if leaving it like that for a long time will deform the neck. So should I tune down the rest of the strings to even out the pull or its ok to leave it as it is? Thanks.
Theoretically, you should tune the rest of the guitar high not low until you replace it, but even if you managed to judge the exact tension difference & not make a mess of it all, then
- it would be so minor as to make no practicable difference overall &
- any practicable difference it did make would also be contributing to twisting the neck very, very slightly out of true.
Fix is to just buy a new set of strings, or even spend a whole quid/buck/shekel on the one missing string... as it's probably pretty much unplayable with only 5 on anyway.
